Cupric ion complexes of histidine-containing peptides.
The binding of cupric or zinc ion by sperm whale metmyoglobin appears to involve imidazole groups of histidyl residues (4, 5) that occur well removed from the NH2 terminus (6). The binding of each cupric ion by metmyoglobin is accompanied on the average by the displacement of one or more protons beyond that that may be borne by the imidazole group, presumably from peptide amide nitrogen atoms (...
متن کاملPolyvinyl alcohol particle superficial morphology.
We appreciated the research by Derdeyn et al (1) from the Mallinckrodt Institute of Radiology concerning the size and suspension characteristics of polyvinyl alcohol (PVA) particles. We do agree that both size and suspension characteristics of PVA represent relevant parameters affecting the aggregation of particles during injection. In addition to these two variables, we considered further para...
متن کاملFabrication of Polyvinyl Alcohol/Kefiran Nanofibers Membrane Using Electrospinning
The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...

Widespread studies on the biodegradation of plastics have been carried out in order to overcome the environmental problems associated with synthetic plastic waste. Recent work has included studies of the distribution of synthetic polymerdegrading microorganisms in the environment, the isolation of new microorganisms for biodegradation, the discovery of new degradation enzymes, and the cloning o...
متن کاملThe Polyvinyl Alcohol Sponge Model Implantation
Wound healing is a complicated, multistep process involving many cell types, growth factors and compounds(1-3). Because of this complexity, wound healing studies are most comprehensive when carried out in vivo. There are many in vivo models available to study acute wound healing, including incisional, excisional, dead space, and burns. Dead space models are artificial, porous implants which are...
